Comment:
The father of Judith, wife of Earl Waltheof, has been widely reported as either
Lambert, Count of Lens, or Enguerrand, Count of Ponthieu, previous husband
of Adeliza. Greene follows Catherine Morton and Hope Mutz, ed. Carmen
de Hastingae Proelio (Oxford, 1972), 126-28, in assigning paternity to
Enguerrand of Ponthieu, though Frank Barlow, in his 1999 edition of the Carmen
de Hastingae Proelio, retains the idea of the Lens paternity. I here
present the traditional Lens filiation, though it is essentially a guess.
